GLASS-BEVELING nrncnrrnn.

T0 allftoi om z'zf mdy concern:

Be it known that I, GEORGE M. Tanni- MEL, a citizen of the United States, residixig at Two Rivers, Manitowoc county, Nisoonsin, have invented certain new and useful Improvements in Glass-Bowling Machines of which the following is a specification.

This invention relates to an improved machine for cutting the bevels on the edges of glass plates I provide a long main trackway of a form similar to the bed of a metal planer and on this trackw'ay is mounted a movable carriage for properly: supporting the glass plate to be beveled. Alongside this tra-ckway is disposed, a return trackway and at the ends of the trackways there are provided transferring turntables. A

carriageway move along the main track- Way and be transferred to and return on the return trackway, and so on in acnecult.

The glass plate is so supported on the 1 @carriage that its surface is at such angle to the horizontal as corresponds with the v angle of thebevei to be produced on the edge of the glass and, at one side, and in an early portion of the-length of the main trackway, there is mounted, on a vertical axis, grinding wheel, preferably of cupped term, to operate on the margin of the glass with its flat face. Several of these grinding wheels may be arranged in succession near each other. Power mechanism reciprocate's the carriage on that portion of the main trackway correspondingwith the set of grinding Wheels referred to, and, as

the carriage reeip'rocates, the grinding wheel or wheels cut away the glass and produce the roughing work on the bevel to be fproduced.

The roughing having been produced the carriage is disconnected from its reciproeating mechanism and is shifted farther along upon the main trackway and again I set into reciprocation, but this time in con- Junctwn with grinding wheels of finer qual- .ity to produce the finishing out upon the glass and when the finishing is: done, the carriage is shifted farther along on the mam trackway and the bevel/of the glass subjected to the action of bufing mecharusm, there being, disposed along the main Spe'eificetion of Letters istent. Application menacin es, ieii.

and by it transferred again to the main ti'ackway, the new ed is of glass plate now going throt process before described. vZlhore inn, he any desired number of the carriages arrange-cl in succession so that while one glass plate is being suhjeeted to the roughing operation another plate may be subjected to the finishing opera tion, and another plate to the bufiing operw tion, and another piste to readjustment to bring a new edge of the plate to position for being operated upon.

A given car iag reciproeated past the tomatic reciprocating means, and when the Work of that grinding agency is over the carriage may be shifted hand to the field of the nestgrindin a ncy and there put in connection with. send automatic reciprocating zneoha In and so on, and. the carriage 'l'lldy he sh d by hand from the main traolrway to the first turntable and then along the return tracizwa-y and then to the second turntable and hack to the main trackway. il hile the carriage is recipr eating upon the main traclrway it has an accurate motion thereon, and when the carriage is to he shifted by hand ant-ifriction wheels are brought into play to slightly elevate the carriage from the sides of the trefekway and perniit the carriage to be easily sh fted along the track by hand.

' Normally, the. carriage will be in sliding engagement with the trackway, but by .15

manipulating handle 16 the load of the carriage may be put upon the wheels thus permitting the carriage to be shifted along the trackway by hand. While the carriage is making its active motions past the grinding agencies, which it does while on the main trackway, the carriage will have an accurate sliding motion on the trackw'ay. The main trackway, as will be later explained, is divided into several successive sections of operations, four in the illustration, somewhat separated from each other and the carriage,

while sliding in these sections, is to be operated by ower, but when the carriage is to be fleeted om one section to the other or onto and off of the turntables or along thereturn trackway, the carriage wheels are to be brought into action and the carriage moved n by hand.

The tapered ends of the note will cause the idle linger, in approaching the nut, to rise and slide till its ti:1ii "eise rib can. en gage with nut. The carriage,- may thus be shifted to nucceeeive operating sections of the main trackway and, if desired for any reasoin may be shifted back to preceding operating section.

It has been assumed that when the carriage is lllUVtd lil'OllllllQ first operation section into the second operating eection, the nut of the second operating section will. he in ouch position as to be engaged by the linger while the carriage is in such a posi lion as: to bring" the tappctarm between the tappcts oi? the StCtilltl o 'ierat'ing section. llut it may well happen that when the carriagre ia ehitted to the second operatingsection the not of that section is found outside the normal range oli travel of the carriage. and in such case, if the linger were engaged with the nut and the tiappet-arm permitted to swing inward to normal position, the I'appet-arni might engage the outer instead oi? the inner face of one of the tappole which would be highly undesirable. 'lherctorc, in such event; the nut having been engaged by the finger, the tappet-arm is to he swung outward by hand, the slot in connection 30 permitting this, and the carriage may be allowed to travel until the tappcl-arm can swing down properly hctween the two tappets.

When one edge of the glass plate has had bevel ientlrely completed the carl'la is to be run upon the right-hand 043 to 'ntable and transferred. to the return track the circumferential groove in the and then put uponthe lcfthand turntable where the plate may be turned to bring a new edge into position to be operated upon, after which the carriage iS run upon the initial end. of the main trackway for the beginning of the beveling operation on the new edge. When all of the edges of the glass plate have been completely beveled then the plate may he removed and a new one placed upon the carriage.

It is manifest that the turning of the glass plate on the carriage, to bring a new edge into position to be operated upon, and the removal of the finished plate and the substitution of a new plate, may be effected at any desired point in the travel of the carriage, hut economy of operations makes it preferable to do this work while the carriage is on the letfthand turntable, as that turntable represents the stage of carriage travel jdst preceding the beginning of beveling operations at the initial end of the i m ai n tr a c kw ay.

Consideration is now to be given the instrumentalities arranged along the length of the main tracln": y for produoin the l'JGVGl. on the edge of the glass plate, it ein understood that the plate will be supporte by the carriage, in a manner hereinafter explained, in such manner as to present the plate at proper beveling angle to the grind ing instrumentalities.

Then, the grinding' progz'esses, bend-Wheel 48 is manipulated whereby the entire group'of grinding stones elevated, pvogressively,

until the desired 'WQFlK the roughing wheels is completed. "When the next edge oi the plate, or snew plate is to be subjected to the roughing operation, the several grinding-wheels will not require individual adjustment except in cases where one of the grinding-Wheels shows excessive wearing away,

The objeci; of having" a series of the roughing' Wheels is io lessen the travel of the glass plate. For instance, if the plate be several feel, wide there need be bus :1 short travel,

say 11 foot or so, in the roughing operation, and with very short pistes one or two grindingwvllecls may be :1ll--sulii-cienb in other Words, indoing the coughing on Wide plates it is not necessary to run the plate ofi of the entire series oi" wheels, extreme accuracy not being called ion in the roughing operation. This permits a very considerable shortening of a, machine adapted for wide plates and, in addition to this, the simulieneous ogerw wheels shoriens the time reqnir'ed in be rongbing operation.

The plate having had its bevel roughed in the first opei'stin goes to the second operating-section wliic by means of the medium grinder past which section of the trackwa,

the plate is reciprocated, has put upon it a further and more accurate beveling. After this the plate goes to the third operating section Where the finishing grinder gives to it the final cutting finish ready for buffing.

The bo'fing cylinder is then i0 be vertically adjus'ed, by means of screw 63, to bring its periplieryinto proper buffing relationship withfiliexbevel "of the glass. The buffing cylindertben'procceds to operate upon the bevel of the gloss, the cylindex reciprocating inward and out-ward of the bevel so as to comprehend the entire surface of the bevel, and at the same time some degree of recipiocation is to be given to the glass to avoid the evil of pronounced transverse markings due to buifing, Very little reciprocation will answer the purpose and if the reciprocation be carried to considerable extent no harm can be done,

Attention will now be even to the con" sz'uclcion of the carriage ad opting it for thklll? proper holding of a plate of glass and for permitting the plate tobe adjusted to suit the bevel desired.

yohes engaging the cams: 8t, posts slidingly connecting the clamp with the yokeS: 9G, tunings: acting between the Clamp and the yolres to cause the descent of the yokes to exert elastic pressureupon the clamp: 91, a lever East on earn-shaft 86: 92, a fixed delent segment engaged by detont mechanism on lever 91 to hold the lover in adjusted poaition: 5 3. a series of lifting shafts disposed under talilo 7-1 par: llel with each other: 94, a nun'd'ior ofarms: fast on each of these lift in; shafts and projecting upwardly therefrom: 95, a roller on the upper end of each of arms 94-. these rollers working up throiuzli openings in the table and adapted, as; the arms are swung; upward. to project above the upper surface of the table: 96. a linl; extending at right angles to shafts 93 and connected with one of the arms 94 on each of those shafts: and 97, a hand-lever Fast. with one of shafts A plate of glass having been placed upon the tahlo. the tahle having been put or to he later put in proper angular adjustment with reference to the rarriago-base lever 91 is; to he manipulated to bring the clamp down upon the glass or upon such cushioning: subetanoo as may be interposed between the if n'npand the glass. Afi'airs are now in condition to subject the margin of the glass-plate to the action of the roughing wheels.

"When the Work is finally done upon the edge of the and it is desirable to lift the plate and to turn it to put. a new edge into proper position relative to the tahlo,

be released and thcrnas before stated. it will often be found that the plate tenaciously adheres to the table. Hand-lever 97 is now to be actuated to move rollers 95 upwardly. the result being that the plate not; only forced up from the table. hut the plate is temporarily supported on rollers tending to facilitate (Qli'ltlfi ma nipnlations of the plate. lVhile the plate is being readjusted the plate may find SIIP- port upon the rollers free from the client of the adhesion which might take place be tween the plate and the table, and at any sesame time before or after the adjustment of the plate upon the table has been efiected the lifting handle may be released and theplate permitted to come down 'solidly upon the table. L

In setting a new plate of glass upon the table, or in turning a plate and bringing a new edge into position for action, itis desirable to avoid the necessity for measuring a relationship-of the edge of the glass to the table. Understanding, as has been before adverted to, that it is preferable to remove and place and adjust the plate of glass while its carriage is on the initial turntable d, I provide at that turntable, in preference in any other point upon the machine, a gage t9 facilitate the settin'g of the plate of glass.

' 'Gontinuing with the-drawings :98, indicates a standard'rising from turntable 4:

and '99, a gagecarried at the top of the. standard and adapted to be engaged by the .edge of a plate of glass properly" clamped upon the table. e

A platefof .g lass' having been properly set .upon the table andg'age 99 having been set ,a gainst the edge of the plate. and fixed, that gage will thereafterserve in settingother edges of similar glass plates, either other eitlges of the same plate orthe edges of other plates. The adjustability of the gage is ngtessential but it is highly desirable in view of the fact thatrthe overhang of the glass plate beyond the edge of the table should not be more than is necessary to provide for grinding the proper bevel, and this is especially true with thin plates.

Mention has heretoforebeen made of ad-.

justing the grinding agents upwardly as the grinding proceeeds but it is to be understood that this is necessary only in case the margin of the glassplate. being operated upon has no movement of its own, as, for instance, if the glass plate were fixedly secured to the carriage at the proper angle for the desired beveL But in the present instance, where the glass plate tips upon the slides along over the flatsurface of a wheel, forming a chord to the circle of the wheel, loose grains of abrasive material are apt tobe carried aggressively against the face of the plate'within the beveled margln and damage the flat surface of the plate. -To av oid this I setthe axes at a slight angle to'the face of the bevel, as will be apprehended from Fig. 8. The face of the wheel being flat testart on it shortly wears to a bevel and the glass will not-be acted upon by more than half of the length of the chord of the wheel-circle represented by the bevel. Under these conditions the loose grains of. abrasive material, instead of doing damage to the clear. face of the glass, become crushed under the buffer and do no harm Mention has been made of the fact that in the series of roughing wheels -the alternate wheels turn in one direction and the inter mediate wheels in the opposite direction- This causes the scorin'gs produced by one wheel to be crossed'by and fairly-compensated for by the scorings of the next wheel, thus materially lessening the duty of the intermediate and finishing grinders.

Provision is made for verti ally-gaging the grinding wheels, this bein done by a gage, roller ada ted to engage the face of the grinding w eel while it is being adjusted, thistnatte'r being best illustrated in Fig. 5 in which :100, indicates .a bracket supported 'by the housing of the grinding wheel: 101, a lever pivoted to the bracket and having an end projecting over the rim of the grinder: 102, a roller mounted in the inner end of the lever and adapted to engage downwardly on the rim of the wheel: 103, a spring coiiperating with the'rollerlever and tending to elevate the roller awayfrom the wheel: 104, a top lever pivoted to the bracket over the roller lever: 105, a link connecting the outer ends of the two levers: 106, a hollow adjusting screw threaded through a portion of the bracket over the free end of the upper lever: and 107, a heads ed pin passing t rough the adjusting screw and having its lower end in engagement with the upper lever;

Adjusting screw 106 is to be so adjusted that when the pin is depressed till its head comes 'ineontact with the top ofrthe screw, the gaging roller will be brought-down to the level at which the surface of the grinding-wheel should be. The pin is to be depressed by hand whenever gaging of the grinding wheel is to be done and when the pin is released then the rolleraat once rises from the grindin whe'elthus avoiding wear.
